HEATER.

Application filed June 14,

To all whom it may concern:

Be it known that I, Ami-run \V. MINNEY, a citizen of the United States, and a resident of Lbs Angcles, in the county of Los Angeles and State of California, have invented certain new and ,useful Improve ments in Beaters, of which the following is a specification.

This invention relates to heaters and is more particularly directed to r a heater adapted for use in the preparation of or ticles of food. f

'An object of the invention is the provision of a strong, durable and easily cleanable beater or mixer which may be readily assembled or disassembled.

g- A: further.object of the invention is the of the same; and;

provision of a heater ormixer in which all the parts that are susceptible to wear are enclosed, so that the ingredients which are being mixed or beaten may not come in contact with said parts.

Another object of the invention is the provision ofa compact sanitary structure which is positive in its action and so c 0nstrut-ted that all the moving parts of the mixer are spaced relative to each other that a minimum amount of wear will be had. 7

Other objects and advantages will become apparent during the course of the following description.

The inventionis llustrated byway of example in the accompanying drawings,in which, v

Figure 1 is a view in perspective of the mixer with partsbroken'away to disclose the internal beater; j

Figure 2 is a horizontal sectional view Fi re 3 is a vertical. sectional view showin t e parts in operative position.

eferring to the drawings, 1 designates a'eylindrical container having a flat circularbottom 2; The bottonn ortion is'pro- =v-ided with a central perforatlon from which isiupwardly extended a vertical sleeve 3, formedintegra-lly with the bottom of the, container; t I r t v The upper; end of the container 1 1so.pen,

within the container an with'the inner wall of the container, an

, sleeve 3.

was. Serial No. 845,366.

The flange 6, snugly fitting the inner wall of the container 1, prevents loss of the ingredicnts when the heater is In operation.

A handle 8 is inounted centrally ot'tlie cover At diametrically opposite points and riveted to the inner face of cover 5 and ad acent its peripheral edges are stationary heaters 9 which are formed integrallvwith the bar 10. The bar 10 is provided with a right angular flange 4 which is riveted to the cover 5. Pointed stationary heaters equally spaced apart and formed oneach bar 10 with a series of the pointed heaters are located on opposite sides of the fixed sleeve 3.

A cylindrical shaft 11 is rotatably mount ed within the sleeve 3 and has a hearing, 12 at the uppcr'extreme end of said sleeve. The bearing is separate from the sleeve and is of such diameter that when forced into the' upper end of the sleeve it wilhre'main' in a fixed position; A second bearmg 13 is mounted in the lower end of the sleeve 3 and is provided with a flange 14 resting on the hub 15 of a beveled car 16 which is pinned to the shaft 11 be ow the bottom of the container 1. The flange 14 of said bearing is in engagement with a the bottom of the container, while the bear-'- ing 13 is forced into immovable'relation with the sleeve 3. A second sleeve 17 telescopes the sleeve 31in spaced relation and is provided with an enlarged closed end'18 having arectangular passa e 19 throu'h which is inserted the square end 20 of t e shaft 11. The-member 18 is spaced from thebearing 12 since thecylindrical por-' tion of the shaft 11 extends slightly beyond the bearingl12 and forms with the squared portion 20 a shoulder spaced? fromihe bmring 12 and upon which-"the member 18 is 17 and the member 18 is'thr'eaded to'receive a winged nut 49 whichflocks said sleeve tothe shaft. .The sleeve? extends downwardly for a. portion'fojjthe -length' "of At diametrically 1 r V opposite points on the andadapted tobe'closed by a coverfi, hawlower end o'f the sleeve 17- are integrally p,

pending arms 21 and 22. Each arm card riesa right angular extension 23 which is a lsteral'flange '1' ads tee te rest epen the directed radially outward from the sleeve upper peripheral edge of the container 1.

3 and adjacent to the base 2 of the container 1. Vertical heaters 24 are formed integrally with or connected to the right angular extensions 23 and are sufficiently spaced from the heaters 9 to pass between said dej'iending stationary.heaters rigidly connected to the cover 5, when the-shaft 11 is rotated.

A bracket 25, which is of angular formation, has a horizontal member 26extending' radially from the shaft 11 and in engagement with the base 2 of the container 1. A second radial arm 27 in alinement with arm 26 is in engagement with the base of the container. The lower end of the bracket has'a lower horizontal arm 28 spaced from the radial arm 27.

A pair of' spaced vertical stand rds 29 and 30 connect the radial arms 27 and 28 together. An auxiliary bracket 3 is integrally formed with the bracket I) and has two vertical standards spaced frtirl each other. At the lower end of the bracket 3]. integrally formed a horizontal clamping arm 32 carrying the screw 33, rovided with a1 knurled knob 34 i' or operating the screw.

A swivelled disk- 35 is adapted to enga e the undersiirface of a able 36. The tab e top is clamped between theidisk 35 and the arm 28.

f The lower end of the shaft 11 is mounted in bearin s formed'in the angular portion 37, of the racket 25. A'second angular portion 38, which is integrally formed with the bracket 21, is perforated and receives the shaft 11 and maintains the QIeeve' -BQ in posi io i The bevelled gear 16 mounted on the shaft 11- below th'e'bearing 13 meshes with a bevelled gear 40 mounted on' a shaft 41, The shaft 41 is mounted in hearings in the standards 29 and-30 and extends through the auxiliary bracket 31. The portion of the shaft 39' located within the bracket, 31 is provided with a toothed wheel 42 over which a chain 43 is directed which likewise embraces a second toothed wheel 44-mountedona shaft 45. Said shaft-is mounted in bearings. at the u(pper ends of bracket 31. A crank- 46 riki ly connected with said shaft, is adapted to operate the samc-..

A circular rest 47 is rigidly secured-"to or integrally" formed with the horizontal radial arms 26 and 27 of the bracket .25 and is adapted to form a support -for the base '2 of the container 1. At diametrically-opposite points on horizontal. radial arms 26" and 27 are formed perforations which are ada'pted to receive lugs 48 for maintaining the container 1 in osition. 1 i

It is particularly pointed out thatall. of the operating parts which are enclosdubetween the sleeves 3 and 17 are spaced from. each other as shown in Figure 3 to prevent wear of said parts when the heater is in operation.

Thesbperation of my device is as follows: .The heaters 24 are ositioned within the container 1 as shown in Figure 3, with the nut 49 t ightened' for locking the sleeve 17 the shaft 11.' Whatever ingredients desired to be beaten or mixed-are placed within the container'when the top 5 is-locatm-l in position with the heaters 9 depending from said top and projecting into the. container. The crank 46 is then operated, operating the shaft 45, chain 43, gears 44 and 4,2, shaft 41 gears 40 and'16 and shaft 11. Rotation of the shaft 11 causes rotation of tlic sleeve 3, arms 23 and the heaters 24.

The annular depending flange 6 of the cover 5 cooperating, with the lateral flange prevents 03s of any of the ingredients from the mixer when the same is in operation.

It will be noted thatthe heaters 24 out through the ingredients and between the stationary paddles 9 whereby the ingredients in the container 1 are tboroughl beaten or mixed. This heater or mixe'i wi 1 beat or mix eggs, frostings,-coatings, mayonnaise, cake dough. pancake-dough, custards, sauces, whipped cream, egg nngg milkshake, batters of all kinds, and in fact any thing except stifl bread-dough.

When it. is desired to remove the beaten ii:- gredients of the container, top 5 is raised with beater 9. Nut 49 is then unscrewed.

The container may be freely lifted'ofi its po-,
